How to upload or replace results to PIX4Dcloud

It is possible to upload outputs to PIX4Dcloud without (re-)processing the images on the Pix4D servers. However, there are some processes that need to be run on the cloud in order to generate the visualization files that are displayed in the PIX4Dcloud viewer. As those processes take some time, the outputs will not be visible right away.

Which files can be uploaded as results
For a new dataset (no images are processed on PIX4Dcloud)
For an existing dataset that was already processed on PIX4Dcloud or whose results were already uploaded
3D OBJ Mesh upload recommendations

Information: For existing projects that were processed on PIX4Dcloud, uploading outputs does not delete the processed results. The new outputs only replace the results.

Information: We recommend that the outputs uploaded to PIX4Dcloud are given in a projected coordinate system.

      

Warning: If a project has been partially processed in PIX4Dmapper, the upload to PIX4Dcloud for processing would repeat the process again, for exmaple:

  • A user has processed step1 and step 2 in PIX4Dmapper and the point cloud and 3Dmesh have been generated.
  • The point cloud is edited in PIX4Dmapper
  • The project is uploaded to PIX4Dcloud
  • Step1 and Step2 will be processed and the point cloud in PIX4Dcloud will lose the editing done in PIX4Dmapper
 

Which files can be uploaded as results

Read the full list of supported files and the required formats at: Inputs.

For a new dataset (no images are processed on PIX4Dcloud)

To upload results to a new dataset:

  1. Go to PIX4Dcloud and log in with a valid Pix4D account.
  2. Create a new dataset and follow the instructions to Upload processed results.
  3. In the Files & Reports > Results section click Upload File in the box of the output to be uploaded, and browse for the directory to select the file. Alternatively, it is possible to drag and drop the file(s) onto the respective output section.
  4. The upload window pops up showing the upload status. Once successful, click CLOSE.
Warning: If you are uploading a 3D textured mesh, read our recommendations here.

Warning: If the outputs are given in a geographical coordinate system (e.g. WGS84), there are some limitations in the user interface:

  • The cartesian coordinates (X,Y) are not correct as a geographical coordinate system is using angles (latitude and longitude)
  • All of the measurements (distances, areas and volumes) are not correct as they are based on the cartesian coordinates.
      

For an existing dataset that was already processed on PIX4Dcloud or whose results were already uploaded

To upload or replace files for an existing dataset:

  1. Go to PIX4Dcloud and log in with a valid Pix4D account.
  2. Open the existing dataset where to upload the output(s).
  3. In the Files & Reports >  Results section click Replace File in the box of the output to be uploaded, and browse for the directory to select the file. Alternatively, it is possible to drag and drop the file(s) onto the respective output section.
  4. The upload window pops up showing the upload status. Once successful, click CLOSE.
Warning: If you are uploading the 3D textured mesh, read our recommendations here.

3D OBJ Mesh upload recommendations

The 3D OBJ mesh generated is not georeferenced. When using PIX4D products, a file named  offset.xyz is generated together with the mesh files. We recommend to upload that file too in the following cases:

  • Both the point cloud and the 3D textured mesh are being uploaded, otherwise, they will not be aligned.
  • A georeferenced 3D textured mesh is needed.
  • Annotations are planned to be created and visualized both in 2D and 3D.
Important: Ensure all four files are uploaded at the same time.
  1. Copy the offset.xyz file in the 3d_mesh folder.
  2. Drag and drop the .obj, .mtl, .jpg and .xyz files in the Mesh OBJ box of the Files & Reports > Results view.
  3. Wait for the upload to be finished. The upload of the georeferenced Mesh is completed.
Important: The texture of the OBJ 3D textured mesh must be a single JPG image. It is not possible to upload to PIX4Dcloud more than one JPG image as the texture of an OBJ 3D textured mesh.
 
To upload an OBJ 3D textured mesh whose texture is more than one JPG image, do one of the following:
  • Generate a new OBJ 3D textured mesh whose texture is a single JPG image.
  • Merge the texture of the existing OBJ 3D textured mesh into a single JPG image.
